OFDM system is Orthogonal Frequency Division Multiplexing system where the sub-carriers are orthogonal to each other. This indicates, non-overlapping of sub-carriers, which results in efficient spectrum utilization. Along with efficient spectrum utilization OFDM has high data rate as one of its advantages. Although tremendous progress has made in the past years to eliminate the Inter-Block Interference (IBI) but still it is considered as area of concern in orthogonal frequency division multiplexing system. The authors proposed interference alignment based channel independent precoding in MIMO OFDM system.
